This paper attempts to provide an interdisciplinary concept of the bio-economy in the context of environmental changes in the Polish agriculture. Various definitions of bio-economy have been presented and its place in the sustainable development theory has been described. The aim of this paper is to present the environmental changes in Polish agriculture in the context of the bio-economy. For this purpose uses the information published by the Central Statistical Office and Eurostat. To showcase and presentation methods were used descriptive and tabular.

Agriculture has been essentially the backbone of economic growth for centuries. The sector has provided employment for the majority of the world population for generations, and has served as a powerful force in transforming of economies towards an industry- and service- based. In many countries, through both productivity increases and farm land expansion, agriculture contributed to the transformation by releasing labor force for the other parts of the economy, providing food security, keeping wage down by providing low cost food, and generating foreign exchange.

Even though a large majority of poor households are engaged in agriculture, per capita productivity and real levels of sectoral growth remain low in Madagascar. Approximately 80 percent of the population are engaged in agriculture, which provides the main source of income for households, albeit at subsistence levels. Cultivation practices are based on extensification strategies with implications for Madagascar’s fragile natural resource base, rather than improving the productivity of existing farms and land use.

Most cities in developing countries fail to treat their wastewater comprehensively. Consequently, farmers downstream use poor-quality water for irrigation. This practice implies risks for farmers, consumers and the environment. Conversely, this water supply supports the livelihood of these farmers and other stakeholders along the value chains. Linking safer options for wastewater management with irrigation could therefore be a win–win solution: removing the risks for society and maintaining the bene ts for farmers.

Large-scale agricultural land investments in Africa are often considered solely from the land perspective. Yet land, water and other natural resources are closely interlinked in agricultural production and in sustaining rural livelihoods. Such investments involving irrigation will potentially have implications for water availability and utilization by other users, making it imperative to regard water as an economic rather than a free good.

The absence of either state regulations or markets to coordinate the operation of individual wells has focussed attention on community level institutions as the primary loci for sustainable groundwater management in Rajasthan and Gujarat, India. The reported research relied on theoretical propositions that livelihood strategies, groundwater management and the propensity to cooperate are associated with the attitudinal orientations of well owners in the Meghraj and Dharta watersheds, located in Gujarat and Rajasthan respectively.

Recent studies show that carbon

sequestered by trees on agricultural

land is not well accounted for. If it was,

researchers argue in a new study: “Global

Tree Cover and Biomass Carbon on

Agricultural Land: The contribution

of agroforestry to global and national

carbon budgets,” total carbon estimates

from agricultural land could be more

than four times higher.

This study examines the socioeconomic features that underpin the expansion of groundwater-dependent irrigation in Northern State, Sudan. Groundwater development in the region serves as an economic lifeline given the poor Nile-based irrigation infrastructure and future changes in Nile hydrology. Groundwater-dependent irrigation is found to be expanding in previously uncultivated regions increasingly distant from the Nile.

Recovering energy from waste offers dual benefits – a) improved waste management, and b) provision of reliable energy to households, institutions and commercial entities. In this report, we present a socioeconomic assessment of three energy business models (briquette manufacturing, on-site (public toilet) energy generation, and agro-waste electricity generation) based on feasibility studies carried out in the city of Kampala, Uganda.

Human wellbeing and food security in a changing climate depend on productive and

sustainable agriculture. For this, policies based on analyses and research results are vital to

establish conservation priorities of natural resources that underpin the enhancement of

sustainable food production. Therefore, data from agrobiodiversity and wider biodiversity sources
